A514 Gr.Q steel Description

ASTM A514 Gr.Q carbon and low-alloy steel is the quenched and tempered high strength weldable steel plate under ASTM standards. It is often shown in the drawings as ASTM A514 Gr.Q, A514 Gr.Q, A514 Grade Q, ASTM 514 Gr.Q, ASTM A514 Q/A514 GRQ. A514Gr.Q carbon and low-alloy steel has high strength and good fatigue resistance; High toughness and low brittle transition temperature; Good cold forming performance and welding performance; A514 Gr.Q high strength low alloy steel has good corrosion resistance and certain wear resistance.

A514 Gr.Q High-strength low-alloy steel plates are mainly used in places where high tension and high yield are required, such as various oil derricks, cranes, high-temperature fans, large shovels, dump trucks and drilling rigs, coal mine hydraulic supports, steel structures, etc. A514 GradeQ steel is a high-strength quenched and tempered steel for large thickness structure through low carbon equivalent composition design and controlled rolling and controlled cooling+quenching and tempering production process. A514 GradeQ is one of the eight common specification grades under the ASTM A514 steel plate standard, and the common thickness of A514 GradeQ under the ASTM A514/A514M standard is 6 inches, about 152.4 mm.
